Talking point: Using a condom isn't as effectiveor as easyas you think.
Fact: Condoms are almost as effective for preventing pregnancy as the Pill when they are used correctly. Condoms also drastically reduce the chance you'll pick up a sexually transmitted infectionand you can't tell by how someone looks if they have one.
Additional advice: "A couple may not put on a condom until the last minute," says Paul Fine, MD, associate professor of gynecology at Baylor College of Medicine in Houston, "and in the heat of passion, he might not have the control he usually has, so that's never foolproof." Besides, you can get pregnant before ejaculation; so-called pre-ejaculate is "loaded with sperm," says Dr. Fine. A 2002 study of college students documented typical condom misuse, slippage, and breakage. Of the men surveyed, 40% said that they had failed to leave space for ejaculate at the tip of a condom, for instance, and 15% had taken the condom off before completing intercourse.
Talking point: If you have unprotected sex or the condom breaks, emergency contraception is an option.
Fact: Plan B is a high-dose birth control pill that is available over-the-counter and can prevent pregnancy if taken within 72 hours, though it is most effective when taken right away.
Additional advice: Many women's health organizations recommend purchasing it before you need it, so that it's readily available if you ever do. Call a doctor, a health clinic, a pharmacy, or a Planned Parenthood office, or place an overnight order from Drugstore.com.
Talking point: Teens and young adults can be at high risk for STDs.
Fact: Young people ages 15 to 24 represent 25% of the sexually active populationbut they account for almost 50% of new STD cases, according to a 2006 Centers for Disease Control and Prevention surveillance report.
Additional advice: Depending upon your child's sexual behavior, testing might vary from frequent (once every few months) to occasional (once every two years, in the case of a monogamous relationship, for example). "Young people ought to get tested once a year for HIV, syphilis, chlamydia, and gonorrhea," says H. Hunter Handsfield, MD, a clinical professor of medicine at the University of Washington and a nationally recognized STD expert who has helped develop HIV testing guidelines for the CDC.
